Suspect regular data on forms about university training initially (5)
I believe the answer is:
doubt
'suspect' is the definition.
(synonyms)
'regular data on forms about university training initially' is the wordplay.
'regular' means one should take alternating letters.
'forms' is an anagram indicator.
'about' indicates putting letters inside.
'university' becomes 'U' (abbreviation as in UMass).
'training initially' becomes 'b' (I can't justify this - if you can you should believe this answer much more).
'data'+'on'='dataon'
The alternating letters of 'dataon' are 'dto'.
'dto' with letters rearranged gives 'dot'.
'u'+'b'='ub'
'dot' enclosing 'ub' is 'DOUBT'.
Can you help me to learn more?
(Other definitions for doubt that I've seen before include "Disbelieve (someone)" , "Feel uncertain about" , "Uncertainty, mistrust" , "Don't be so sure!" , "Misgiving" .)
